In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Reciprocity is a fundamental physical principle that roots in the time‐reversal symmetry of
physical laws. It allows making predictions on any arbitrary complex system's response and …

Circulators are nonreciprocal circuit elements that are integral to technologies including
radar systems, microwave communication transceivers, and the readout of quantum …

Incorporating ferromagnetic dopants into three-dimensional topological insulator thin films
has recently led to the realisation of the quantum anomalous Hall effect. These materials are …

Photonics and optoelectronics are at the foundations of widespread technologies, from high-
speed internet to systems for artificial intelligence, LiDAR, and optical quantum computing …

Microwave plasma as a potential tool to convert CO 2 has been extensively studied in recent
years. A simulated study on the plasma parameters via the variation of the operating …

We present a model study of an alternative implementation of a two-port Hall-effect
microwave gyrator. Our setup involves three electrodes, one of which acts as a common …

Quantum Hall edge states have some characteristic features that can prove useful to
measure and control solid state qubits. For example, their high voltage to current ratio and …

We develop a theory that describes the response of nonreciprocal devices employing two-
dimensional materials in the quantum Hall regime capacitively coupled to external …

The characteristic impedance of a microwave transmission line is typically constrained to a
value Z 0= 50 Ω, in part because of the low impedance of free space and the limited range of …
